I actually enjoy visiting old buildings, museums 'n' such......Historical Districts.....I can drive to many here in the South, and the ones I can't drive to, I can see online.........I'm just weird that way.
The years I lived overseas (mostly in Europe), I saw so many wonderful places........too many to even begin to list.
But, if I was forced to narrow it down, I suppose the West Coast of France, and the Channel Islands.....especially the Isle of Jersey would be very near the top, if not No. 1.
